SEALING ATTACHMENT FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 598,929, dated February15, 1898.

Application filed February 15, 1897. Serial No. 623,361. (No model.)

To aZZ whom it may concern:

Be it known that 1, ROBERT HEARNS, of St. Paul, Ramsey county,Minnesota, have invented certain Improvements in Sealing Attachments forBottles, of which the following is a specification.

My invention relates to improvements in bottles, its object being toprovide an improved sealing attachment for the bottle, preventingrefilling of the same after it has been emptied of its contents.

To this end my invention consists in arranging in the neck of the bottlea sealing attachment normally closing the same. This sealing attachmentconsists of a guard-disk secured in the bottle-neck by a spring arrangedin a circumferential groove in the disk and neck. The guard-disk isformed with a downwardly-projecting stem, limiting the movement of avalve fitted in the throat of the bottle. The valve is normally held toits seat by a light spring interposed between it and the guard-disk andis adapted to be opened by the weight of the liquid in the bottle whenthe same is inverted, theliquid passing around the Valve and out throughports or openings in the guard-disk. When the bottle is emptied of itscontents, the valve will be held to its seat by the above-mentionedspring, so as to prevent refilling. My invention further consists in thespecific features of construction and combination of parts hereinaftermore particularly described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a vertical central section of a bottle fitted with myimprovements. Fig. 2 is a detail of the guarddisk, partly in section;and Fig. 3 is a detail of the spring by which said disk is secured inthe bottle-neck.

In the drawings, A'represents the bottle, The bottom of the neck isformed with an inwardly-projecting 'annular flange 3, constituting acentral throat 4.

13 represents the guard-disk, held in place in the bottle-neck by thespring-ring 5, fitting in a circumferential groove 6 in the disk and Theguarddisk is formed with a central downwardlyprojecting stem 8, taperedat its bottom and projecting into a socket 9 in the valve 10. The valve10 is held to its seat by a coilspring 11, surrounding the stem 8 andabutting against the guard-disk and valve. A space is left between theend of the stem 8 and the bottom of the socket 9 in the valve, so as topermit movement of the valve in emptying the bottle.

The guard-disk B is formed with a series of openings 12 to permit theoutflow of the liquid.

In use the bottle is first filled with liquid and the valve 10 thenplaced in the throat 4, as shown in Fig. 1. The guard-disk B is thenplaced in the bottle-neck, the spring 5 expanding into the groove 7 inthe neck and holding the disk locked from removal, the neck being thenclosed by a cork 13in the ordinary manner. The spring 11, interposedbetween the guard-disk and the valve, is of suflicient strength to holdthe valve in the throat 4, but is adapted to be compressed by the weightof the liquid in the bottle to allow the valve to be opened when thebottle is held in inverted position ,the liquid passing around the valveand out from the openings 12 in the disk. After the bottle has beenemptied of its contents it cannot be refilled, as the spring 11 willhold the valve in the throat 4 and prevent the passage of the liquidaround it, so that in order to fill the bottle it will be necessary toremove the above described parts, which cannot be done withoutdestroying the bottle.

The valve is provided with a metallic sheathing 14',which will preventtampering by means of a Wire passed through the openings in theguard-disk, the valve 10 being ordinarily made of a non-metal.

I I claim- The combination with abottle-neck, formed with aninwardly-proj ectin g flange at its bottom constituting a constrictedthroat, the

valve seated in said throat, the guard-disk arranged above the same inthe bottleneck and secured in place bya spring arranged in thecircumferential groove in the disk and neck, said disk being providedwith vertical openings, the downwardly-projecting stem upon said'diskprojecting into an opening in In testimony whereof I affix my signaturesaid Valve, the spring surrounding said stem in presence of twoWitnesses.

and bearing against the disk and valve, and 1 H l T the protectingdevice for said valve prevent- ROBhhl IIEARLS' ing tampering by means ofa Wire or other in- \Vitnesses:
